You can try this simple circle casting that might help. As you walk in a clockwise circle 3 times around what you would like to include in your circle casting say this chant.
I cast this circle thrice about, to keep the negative energies out. A space between the worlds I create, where time stands still and fear will abate.
I gather the strength to build this bond through wind and fire, water and stone. Spirit guide me as I walk this hedge, constructing this place that is a spiritual bridge.
